Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11612 was prepared by Technical Committee ISO/TC 94, Personal safety - Protective clothing and
equipment, Subcommittee SC 13, Protective clothing.
This edition cancels and replaces ISO 11612:2008. It has been prepared in order to:
a) include test procedure for dry-cleaning in normative references;
b) modify clause in design requirements regarding garment overlaps;
c) modify clause in design requirements regarding the areas of the body covered by protective suits;
d) modify clause for ageing due to washing (maximum number of cleaning procedures as indicated by the
manufacturer);
e) modify pretreatment clause to include requirements for single use garments;
f) modify pretreatment clause to specify dimensional stability is carried out after five cleaning cycles;
g) include modified procedure when measuring dimensional stability;
0
h) modify requirement for optional heat resistance testing at 260 C;
i) modify requirement that hardware is tested only after pretreatment;
j) include statement for flame spread testing in regard to interlining materials;
k) modify test procedure for the flame testing of Labels, badges, retro-reflective materials;
l) modify requirements for tear strength;
m) specify test area for burst strength testing;
n) specify limit for CR(VI) Content;
o) update reference in electric arc clause to include IEC 61482- 2;

Introduction
The purpose of this International Standard is to provide minimum performance requirements for clothing to
protect against heat and flame, which could be worn for a wide range of end uses. All the other standards
listed in the Foreword deal also with clothing to protect against heat and fire, but rather for quite specific
products or end uses.
Within many of the hazards listed in this International Standard there are three performance levels:
⎯ Level 1 to indicate exposure to perceived low risk;
⎯ Level 2 to indicate exposure to perceived medium risk;
⎯ Level 3 to indicate exposure to perceived high risk.
For protection against extreme exposures to radiant heat, there is a fourth performance level to take into
account high performance materials such as aluminized and similar materials. The level of personal protection
to be provided is based on the outcome of the risk assessment and some comments on risk assessment are
given in Annex E.
In this International Standard, an informative annex on ergonomic features (Annex D) is included in the form of
guidelines. Suitable tests for these requirements have not yet been validated internationally.
For complete protection against exposure to heat and/or flame, it is probable that it will be necessary to
protect the head, face, hands and/or feet with suitable PPE and in some cases, appropriate respiratory
protection might also be considered necessary.
[1]
Attention is drawn to CEN Technical Report CEN/TR 14560:2004 , which sets out guidelines for selection,
use, care and maintenance of protective clothing against heat and flame.
Nothing in this International Standard is intended to restrict any jurisdiction, purchaser or manufacturer from
exceeding these minimum requirements. It is one of several standards for clothing that have been developed
to protect persons against heat and/or flames. Other standards include:
⎯ ISO 11611, Protective clothing for use in welding and allied processes;
⎯ ISO 11613, Protective clothing for firefighters — Laboratory test methods and performance requirements;
⎯ ISO 14460, Protective clothing for automobile racing drivers — Protection against heat and flame —
Performance requirements and test methods;
⎯ ISO 15384, Protective clothing for firefighters — Laboratory test methods and performance requirements
for wildland firefighting clothing;
⎯ ISO 15538, Protective clothing for firefighters — Laboratory test methods and performance requirements
for protective clothing with a reflective outer surface;
⎯ EN 469, Protective clothing for firefighters — Performance requirements for protective clothing for
firefighting;
⎯ EN 1486, Protective clothing for fire-fighters — Test methods and requirements for reflective clothing for
specialised fire fighting;
⎯ EN 13911, Protective clothing for firefighters — Requirements and test methods for fire hoods for
firefighters;

DRAFT INTERNATIONAL STANDARD ISO/DIS 11612

Protective clothing — Clothing to protect against heat and
flame — Minimum performance requirements
1 Scope
This International Standard specifies performance requirements for garments made from flexible materials,
which are designed to protect the wearer’s body, except the hands, from heat and/or flame. For protection of
the wearer’s head and feet, the only items of protective clothing falling within the scope of this International
Standard are gaiters, hoods and overboots. However, concerning hoods, requirements for visors and
respiratory equipment are not given.
The performance requirements set out in this International Standard are applicable to garments which could
be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties
and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.
This International Standard is not applicable to protective clothing that is specified by other International
Standards, such as for firefighting in structures and for use in welding and allied processes.
